  Context: Autoimmune thyroid disease is the most common endocrine co-morbidity in autoimmune Addison's disease (AAD), but detailed investigations of prevalence and clinical course is lacking. Objective: Provide comprehensive epidemiological and clinical data on autoimmune thyroid disorders in AAD. Design and patients: A nationwide registry-based study including 442 patients with AAD and autoimmune thyroid disease, identified through the Norwegian National Registry of Autoimmune Diseases. Results: Of 912 registered AAD patients, 442 (48%) were diagnosed with autoimmune thyroid disease. Three hundred and eighty (42%) had autoimmune hypothyroidism. Of the 302 with available thyroid function tests at time for diagnosis, 20% had overt hypothyroidism, 73% had subclinical hypothyroidism and 7% had thyroid levels in the normal range. Negative thyroid peroxidase antibodies was found in 32%. Ninety-eight percent were treated with levothyroxine, 5% with combination therapy with liothyronine or thyroid extracts, and 1% were observed without treatment. Seventy-eight patients (9%) were diagnosed with Graves' disease (GD), of whom 16 (21%) were diagnosed with autoimmune hypothyroidism either before onset or after remission of GD. At the end of follow-up 33% had normal thyroid hormone levels without antithyroid-drugs or levothyroxine treatment. The remaining had either active disease (5%), had undergone ablative treatment (41%), or had developed autoimmune hypothyroidism (21%). Conclusion: The true prevalence of hypothyroidism in AAD is lower than reported in current literature. Careful consideration of the indication to start thyroxin therapy is warranted. Long-term remission rates in GD patients with AAD are comparable to recent reports on long-term follow-up of patients without AAD.

  Design: Two-staged, cross-sectional clinical study in 17 centers (Norway, Sweden, and Germany). Residual glucocorticoid (GC) production was defined as quantifiable serum cortisol and 11-deoxycortisol and residual mineralocorticoid (MC) production as quantifiable serum aldosterone and corticosterone after > 18 hours of medication fasting. Corticosteroids were analyzed by liquid chromatography–tandem mass spectrometry. Clinical variables included frequency of adrenal crises and quality of life. Peak cortisol response was evaluated by a standard 250 µg cosyntropin test. Results: Fifty-eight (30.2%) of 192 patients had residual GC production, more common in men (n = 33; P < 0.002) and in shorter disease duration (median 6 [0-44] vs 13 [0-53] years; P < 0.001). Residual MC production was found in 26 (13.5%) patients and associated with shorter disease duration (median 5.5 [0.5-26.0] vs 13 [0-53] years; P < 0.004), lower fludrocortisone replacement dosage (median 0.075 [0.050-0.120] vs 0.100 [0.028-0.300] mg; P < 0.005), and higher plasma renin concentration (median 179 [22-915] vs 47.5 [0.6-658.0] mU/L; P < 0.001). There was no significant association between residual production and frequency of adrenal crises or quality of life. None had a normal cosyntropin response, but peak cortisol strongly correlated with unstimulated cortisol (r = 0.989; P < 0.001) and plasma adrenocorticotropic hormone (ACTH; r = –0.487; P < 0.001). Conclusion: In established AAD, one-third of the patients still produce GCs even decades after diagnosis. Residual production is more common in men and in patients with shorter disease duration but is not associated with adrenal crises or quality of life.

  The current study aimed to assess a possible association between the bone turnover marker procollagen type 1 amino-terminal propeptide (P1NP) and future hip fractures in elderly Norwegian men and women and to elucidate the relation between P1NP, bone mineral density and 25-hydroxyvitamin D (25(OH)D). Men and women aged 71 to 77 from two population based health studies in Norway (1999-2001) were followed for a median period of 7.3years with respect to hip fractures. The study was designed as a case-cohort study. P1NP and 25(OH)D were analysed in frozen serum samples obtained at baseline in hip fracture patients (n=340) and in randomly selected sex stratified sub-cohorts. Bone mineral density was measured by dual-energy X-ray absorptiometry (DXA) in a subset of participants. Cox proportional hazards regression with inverse probability weighting and robust variance was performed. No significant correlation between 25(OH)D and P1NP was found. A negative correlation between P1NP and BMD was observed in women (Rho=-0.36, p=0.001). A similar trend was observed in men. No association between quartiles of P1NP and rate of subsequent hip fractures was found. Spline analyses suggested a higher rate of hip fracture at P1NP levels above 60μg/L in both men and women. A higher hip fracture rate, which was independent of BMD, was also indicated in women with very low levels of P1NP.

  Introduction: Norway has a high hip fracture incidence. Bisphosphonates and denosumab have been shown to prevent hip fractures in clinical trials, but there is a lack of population studies. Aims: To investigate whether use of bisphosphonates and denosumab reduce the risk of first-time hip fracture in Norway when adjusting for morbidity by the medication-based Rx-Risk Comorbidity index. Methods: The population was defined as inhabitants identified in the national census of 2001 who were still alive and resident by 1 January 2005. The Norwegian prescription database (NorPD) supplied data on exposures to bisphosphonates, denosumab, and other drugs for the calculation of the Rx-Risk score. Information on previous and incident hip fracture was available in the quality-assured NOREPOS hip fracture database. Persons 50 years or older were included starting from January 2005 and observed through December 2016. Sex-stratified Cox regression and flexible parametric survival analysis was used with age as time scale and with time-varying exposure to bisphosphonates and denosumab. Individuals were followed until hip fracture or censoring (death, emigration, age 90 years, or 31 December 2016, whichever occurred first). Rx-Risk score was included as a time-varying covariate, updated every two years. Other covariates were marital status, education, and time-varying use of bisphosphonates/denosumab with another indication than osteoporosis. Mean time to hip fracture within the observation period (restricted mean survival time) was estimated for the two different treatment exposures. Results: Of 1,044,661 women and 1,040,782 men, 74,775 (7.2%) and 13,417 (1.3%), respectively, were ever-exposed to either drug. Women exposed to bisphosphonates had a hazard ratio (HR) of 1.09 (95% CI: 1.05–1.13) for hip fracture (age as time-scale), while women exposed to denosumab had an HR of 0.68 (95% CI: 0.53–0.87). The corresponding fully adjusted HRs were 0.95 (95% CI: 0.91–0.99) and 0.58 (95% CI: 0.46–0.74) respectively. Exposure to either of the two drugs gave a longer hip fracture free period in women. For men exposed to either drug, the HRs was well above 1 – also when adjusted. Conclusions: In population-wide real-world data, women exposed to bisphosphonates had a hip fracture risk around the same level as the unexposed population after adjusting for comorbidity. Exposure to denosumab was associated with a lower risk of hip fracture in women.

  Background and Aim: Recent international studies indicate a secular decrease in the proportion of patients with diabetes who undergo lower limb amputations (LLA), and the same trend is observed in the national quality indicator. The validity of electronic databases and quality indicators are limited by multiple discharges and precision of coding. Furthermore, amputation codes included in the quality indicator do not include all amputations. We therefore aim to investigate the recent incidence of LLA in the catchment area of a middle-sized Norwegian hospital, and to compare it with data collected during 1990–99. Methodes: Medical records for all patients identified with LLA by the electronic discharge registers at Innlandet Hospital, Elverum, from 2013 through 2019 were retrieved. All codes for amputations and exarticulations were included, and amputations were verified by manual review by two of the authors. Traumatic and cancer-related amputations were excluded. Both minor and major amputations were included in further analyses. Diabetes was defined by the WHO criteria. The prevalence of diabetes was calculated using data from the Norwegian Prescription Database and Statistics Norway. Results: We identified 169 non-traumatic, non-cancer related amputations in 127 patients, of which 77 had diabetes. The proportion of amputees with diabetes had increased from 44% in the previous period to 61% in the recent data. Ten percent had type 1 diabetes compared to 4% during 1990–99. We estimated that 0.23% of individuals on antidiabetic drugs in the catchment area, underwent an amputation per year in the period 2013–19, compared to 0.31 % in 1990–99. The average absolute number of diabetics undergoing an LLA per year was 11 in both periods. Multiple amputations were common both in persons with and without diabetes and was present in 26% of the amputees, even though a high proportion in both groups underwent vascular surgery before amputation. Detailed information and further results will be provided. Conclusion: Our findings suggest that the proportion of diabetics among patients undergoing non-traumatic, non-cancer related lower limb amputations has increased over the past decades. Multiple amputations are still common, despite comprehensive preoperative investigations and other surgical interventions.

Causes of death and cause-specific excess mortality after hip fracture. The Norwegian Epidemiologic Osteoporosis Studies (NOREPOS). Vis sammendrag

  Background: A hip fracture is a serious injury particularly affecting older people with multimorbidity, and it is associated with high excess mortality. Information on causes of death may help appraise the degree to which this excess mortality reflects pre-existing comorbidities or the hip fracture trauma. We aimed to describe leading causes of excess mortality through the first year after a hip fracture. Methods: Information on all hospital-treated hip fractures in Norway 1999-2016 from the NOREPOS database were linked with age- and sex-matched population controls and the Norwegian Cause of Death Registry through 2017. Underlying causes of death were coded according to ICD-10 and grouped by the Eurostat shortlist. Results: Of 146,132 Norwegians with a first incident hip fracture, 35,498 (24.3%) died within one year. By 30 days post-fracture, external causes (usually the fall causing the fracture) were defined as the underlying cause for the majority of deaths (53.8%), followed by circulatory diseases (19.8%), neoplasms (9.4%), respiratory diseases (5.7%), mental and behavioral disorders (2.0%) and diseases of the nervous system (1.3%). By one year post-fracture, external and circulatory causes together accounted for half of deaths (26.1% and 27.0%). When comparing cause-specific mortality (from causes other than external causes) after hip fracture with population controls, relative mortality risks in women ranged from 1.5 for circulatory diseases to 2.5 for diseases of the nervous system. Corresponding relative risks in men ranged from 2.4 for circulatory diseases to 5.3 for diseases of the nervous system. Early excess mortality (first month) was particularly high in all cause of death categories. Conclusion: Hip fractures entail high excess mortality from all major causes of death. However, the traumatic injury of a hip fracture is the leading underlying cause of death the first year after the fracture, underlining the importance of preventing falls and fractures in older adults.

  Introduction: Norway has a high hip fracture incidence. Clinical trials have demonstrated fracture-preventive effects of bisphosphonates (BPs) and denosumab (DMab). We aimed to investigate whether BPs and DMab used in the population of Norway reduce risk of first-time hip fracture when adjusting for morbidity. Material and methods: Demographic information from participants in the Population and Housing Census 2001 who were alive and resident by 1 January 2005 was linked with filled prescriptions in the Norwegian prescription database (2005-2016) and the NOREPOS hip fracture database. Persons 50 years and older were included starting from January 2005 and observed through December 2016. Sex-stratified time-to-event analysis was used with age as time scale and time-varying exposure to BPs and DMab. The medication-based Rx-Risk Comorbidity Index was added as a time-varying covariate. Other covariates were marital status, education, and exposure to BPs/DMab with another indication than osteoporosis. Results: Of 1,044,661 women and 1,040,782 men, 74,775 (7.2%) and 13,417 (1.3%), respectively, were ever-users. Age-adjusted hazard ratio (HR) of hip fracture in women was 1.20 (95 % CI: 1.15–1.26) when using BPs, and HR 0.74 (0.55–0.99) when using DMab. Fully adjusted HRs were 1.01 (0.96–1.06) and 0.62 (0.46–0.83) respectively. For men exposed to BPs, HR was well above 1 – also when adjusted. Conclusions: In population-wide real-world data, women exposed to BPs had a hip fracture risk around the same level as the unexposed population after adjusting for comorbidity. Exposure to DMab was associated with a lower risk of hip fracture in women.

Individual variation in adaptive immune responses and risk of hip fracture – A NOREPOS population-based cohort study. Journal of Bone and Mineral Research.

  T-cell mediated immune responses may affect bone homeostasis, and subsequently the risk of fracture, through multiple pathways. Little is known about how individual variation in these responses contributes to the risk of fracture on a population-level. Tuberculin skin tests (TST) are likely one of the few tests directly reflecting in vivo T-cell responses to have been conducted on a population-scale, as part of the effort to prevent the spread of tuberculosis. The aim of this study was to estimate the impact of individual variation in these immune responses on the risk of hip fracture in the general population. The hypothesis was that individuals with a tendency towards pro-inflammatory responses have an increased risk of fracture.We used data from the compulsory nationwide Norwegian mass tuberculosis screening and BCG vaccination programme during 1963-1975, which covered an estimated 80-85% of the population. This data included results from standardized TST, as well as timing and status of BCG vaccination. Individuals aged 14-30 years at the time of TST measurement and born 1940-1960 were included in the current analysis. All included individuals had a negative TST followed by BCG vaccination in the past, and had no signs of tuberculosis upon examination. TST results at the screening were recorded in millimetres, and later categorized according to clinical guidelines (positive/negative). Our cohort constitutes 248 551 individuals who were alive and living in Norway at the start of the NORHIP database in 1994. This database includes records on all hospitalizations due to hip fractures in Norway during 1994-2013 (follow-up). Risk estimates were adjusted for county, BMI, age and time between BCG-TST, using Cox regression models. There were 3580 incident hip fractures during follow-up (first fractures), with a median age at the time of fracture of 61 years (range 36-73). Men with a positive TST had a 22% (HR 1.22, 95% CI 1.02-1.44) increased adjusted risk of hip fracture compared to men with a negative TST. This association was strengthened in sensitivity analyses limited to either those born 1945-1960 (post WW2) or aged 11-14 years at BCG vaccination (school vaccination). No clear association was observed in women. We conclude that men with a negative tuberculin skin test after BCG vaccination have a reduced risk of hip fracture decades later. Women do not demonstrate similar associations, potentially due to sex specific differences in immune responses.
